Asthma and Allergies
Peanut allergies can cause severe and sometimes deadly allergic reactions. A new study holds out the possibility that peanuts themselves may prevent peanut allergies. An international team asked parents of infants who were prone to a peanut allergy to give their children a peanut-based snack called Bamba or peanut butter three times a week until age five. The parents of another group of peanut allergy-prone infants were asked to make sure their children didn’t eat any peanuts, peanut butter, or other peanut-based products until age five. The results were surprising and dramatic. A peanut allergy developed in 1.9% of children who ate Bamba or peanut butter, compared with 13.7% of those who didn’t eat peanuts. This new work suggests that preventing peanut allergies may be a possibility in the near future.
After being confined to health-food stores for years, gluten-free foods have become the latest food fad. Supermarket aisles abound with products proudly labeled “Gluten free,” and many restaurants now offer gluten-free options. For people who can’t tolerate gluten, a protein found in wheat, rye, and barley, this abundance is a blessing. But lately it’s become hip to go gluten-free. Based on little or no evidence other than testimonials in the media, people have been switching to gluten-free diets to lose weight, boost energy, treat autism, or generally feel healthier. People who are sensitive to gluten may feel better doing this, but most won’t get a significant benefit from the practice—and will pay more for food because gluten-free products are expensive. It’s important to know that it can set you up for nutritional deficiencies such as a dearth of B vitamins and fiber.
